Yes, there are likely fanfictions out there with this concept. There is a large and creative fanfiction community that often explores different family relationships among characters. You can search on popular fanfiction websites like Archive of Our Own or FanFiction.net to find such stories.
I'm not sure specifically as there could be many different interpretations in such a fanfiction. It might involve a strange power dynamic where Harry is somehow in a subservient position to Draco, perhaps exploring themes of control, rivalry, or unexpected alliances in a very unorthodox way.
He could be really outgoing. Maybe he's the type who makes friends easily and is always the life of the party at Hogwarts. Unlike Harry who was a bit more reserved at times, the younger brother could be constantly getting into adventures and dragging Harry along with him.
This fanfiction concept is really interesting. Harry being Draco's younger brother would mean a different upbringing for Harry. He'd have access to the Malfoy's wealth and status. However, his personality might still shine through. He might be a Slytherin with a heart of gold, trying to change the family's views from the inside. His relationship with Dumbledore would also be different as Dumbledore might see him as more of a 'project' to save from the Malfoy influence.
Well, you could find fanfictions where Harry's relationship with his famous brother is the central theme. It might explore their sibling rivalry, or how they support each other in the face of magical challenges. Some might also delve into Harry's efforts to carve his own identity.
At first, they might have the typical sibling rivalry. Doms could be a bit overprotective as the older brother, which Harry might find annoying. But as they face challenges together, like dealing with school bullies or difficult exams, their relationship deepens and they become closer friends as well as brothers.
Well, in 'harry is dracos pet' fanfiction, themes like friendship in unexpected circumstances are common. Despite the strange setup, the two characters may still develop a bond. Adaptation is another theme, as Harry has to adapt to his new life as a pet. And of course, there's the theme of breaking boundaries. This non - traditional relationship challenges the norms of the wizarding world and how characters interact, which can lead to exploring new social and magical concepts within the fanfiction world.
Well, it could change the story in many ways. For example, if the younger brother is as magically talented as Harry, they might share the spotlight at Hogwarts. He could also be a support system for Harry, especially during tough times like facing Voldemort. Maybe he'd have different relationships with the other characters, like befriending Ron and Hermione in a different way than Harry did.
Yes, there are such fanfictions out there. However, I can't really recommend specific ones as there are so many and their quality varies greatly. You can try searching on fanfiction - specific websites like Archive of Our Own or FanFiction.net using relevant keywords to find them.
They might go on adventures like exploring the Forbidden Forest. Since Harry is Doms' younger brother in this fanfiction, they could be sneaking around the forest looking for magical creatures that are rumored to live there.
